# ----------------------------------- Paths ------------------------------------

#

# Path to directory where to store the data (separate multiple locations by comma):

#

#path.data: /path/to/data

#

# Path to log files:

#

#path.logs: /path/to/logs

#

# ----------------------------------- Memory -----------------------------------

#

# Lock the memory on startup:

#

#bootstrap.memory_lock: true

#

# Make sure that the heap size is set to about half the memory available

# on the system and that the owner of the process is allowed to use this

# limit.

#

# Elasticsearch performs poorly when the system is swapping the memory.

#

# ---------------------------------- Network -----------------------------------

#

# Set the bind address to a specific IP (IPv4 or IPv6):

#

#network.host: 192.168.0.1

#

# Set a custom port for HTTP:

#

#http.port: 9200

#

# For more information, consult the network module documentation.

#

# --------------------------------- Discovery ----------------------------------

#

# Pass an initial list of hosts to perform discovery when this node is started:

# The default list of hosts is ["127.0.0.1", "[::1]"]

#

#discovery.seed_hosts: ["host1", "host2"]

#

# Bootstrap the cluster using an initial set of master-eligible nodes:

#

cluster.initial_master_nodes: ["192.168.1.103:9200", "node-2"]

#

# For more information, consult the discovery and cluster formation module documentation.

#

# ---------------------------------- Gateway -----------------------------------

#

# Block initial recovery after a full cluster restart until N nodes are started:

#

#gateway.recover_after_nodes: 3

#

# For more information, consult the gateway module documentation.

#

# ---------------------------------- Various -----------------------------------

#

# Require explicit names when deleting indices:

#

#action.destructive_requires_name: true
